You could make these using any citrus fruit you like. I just happened to have a bunch of Meyer lemons on hand.
You will need 3 T. of zest and 2/3 cup of juice.
In the bowl of your mixer, beat 1 1/2 C. sugar with 1 C. of softened butter.
Add 1 C. of sour cream and beat until blended and fluffy. Add 2 eggs and beat to blend.
Add 1 tsp. of baking soda, 1 tsp. of baking powder and 1/2 tsp. of salt.
Add the paddle attachment and beat in the 3 T. zest and the 2/3 C. of juice.
Beat until fluffy.
Add 4 C. of flour one cup at a time.
Place walnut sized balls of dough on a parchment covered cookie sheet. bake for 10-12 minutes at 375 degrees until they just begin to brown on the edges.
Make the frosting. Mix 1/4 C. of softened butter, 2 C. of powdered sugar, 1 T. zest and 3 T. juice.
Before going into the oven.
Right out of the oven. Frost as soon as you take them out of the oven. Place a dollop of frosting in the middle of each cookie and move it around so it coats the entire cookie .
It will create a glaze.
These melt in your mouth!
